Ant poison feeder



| A. MATTES ANT POISON FEEDER Filed Aug. 9, 1926 ATTORNEY Patented May 12, 1931 UNETE LEO A. MATTES, F BERKELEY, CALIFORNIA ANT POISON FEED-ER Application filed August 9, 1926". Serial No. 128,028.

My invention relates to insect poison feeders, and particularlyto feeders designed for out-of-door use.

, An object of the invention is to provide a feeder of the class described which utilizes containers of standard form in combination with a unitary cover member of special form.

Another object of the invention is to provide a feeder of the class described in which the cover'member therefor may be formed by a single operation.

A further object of the invention is to provide a cover member for a feeder of. the class described which not only provides insect passages over the lip of the container but also provides gripping means for resiliently holding it operatively disposed with respect to the container. I

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of .my invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood, however, that I do not limit myself to the showing made by the said drawings and description, as I may adopt variations of the 30 preferred form within the scope of my invention as set forth in the claims.

' Referring to said drawings,

Figure 1 is a side view of one embodiment of the feeder.

Figure 2 is a side sectional view of the .feeder.

Figure 3 is a bottom View of the feeder.

In insect-poison feeders, and particularly in those designed to provide poisoned food for ants, it has been the usual custom to provide a poison container having perforate walls or a notched lip, and a cover for such container, which cover is arranged to have a portion which extends below the cover seat and is disposed outwardly of the passages. Such structure has, of course, involved a special construction for both the container and cover and such construction has proved an important factor in production costs. In accordance with my invention, however, I am enabled to utilize containers of standard form so that only the cover structure is a special one, and have so formed the cover that it can be made by a single die-stamping operation, thus effecting an appreciably lowered production cost for the complete device.

As herewith particularly illustrated, the feeder 4 comprises a container portion 5, here shown as a drinking orjelly glass of usual outline, and a cover member 6. The

' exterior surface 7 of the cover 6, it will be noted, is preferably of generally convex outline,-so that the shedding of any moisture which may fall thereon maybe insured, it being noted that the feeder is thus particularly arranged for out-door use.

Defined within the cover 6 is a cavity 8 in which the lip 9 of the container is arranged to be releasablydisposed. As here shown,

form the cover 6 of a non-corroding sheet metal such as aluminum and that the cover is of such form that it may be shaped from a blank by a single operation of a suitable die. A further advantage of the use of sheet metal lies in the fact that,'by reason of the fluted structure of the cover edge, the engagement of the cover edge with the lip of a container of slightly greater circumference than that defined by the cover portions 12 provides for the resilient engagement of the latter with the container lip, so that the cover will be resiliently held seated on the container. In this manner, the provision of insect passages and cover fastening means are both solely functions of the cover structure provided.

While it will, of course, be obvious that the shape of the container may be other than that here shown, the use of a container shaped as illustrated is particularly advantageous since glasses or wide mouthed bottles of standard form may be used without any structural alteration thereof, as the cover member provides the. necessary admission passages and cover securing means.

I claim:

1. An insect-poison feeder comprising a container having an open upper end pro- Vided with an annular rim located in its entirety in a common plane and a flanged resilient cover fitted over and holdingly en gaged with the open end of the. container, said cover having indentations at spaced points arranged to engage said-rim and to define: insect entrance openings between said indentations and said rim and cover, the flange of said cover being spaced outwardly from said container to permit of access to said insect entrance openings.

,2. An insect-poison feeder comprising a poison container having an open end the rim of which is in its entirety disposed in a common plane, andan inverted cup shaped cover-made of a single piece of -resilient material and telescoping the open end of said container in frictionalholding engagement therewith, said. cover having indentations thereon at the juncture of the body and flange portions, which indentations engage said rim and define betweenthem andthe rim, and cover insect entrance openings.

In testimony whereof, I have hereunto set my hand at Oakland, California, this 3rd day of August, 1926.
